Add EVMBridgedMetadata view implementation

Related: #213

Description

Adds implementation of EVMBridgedMetadata for both contract and token-level metadata.

Note: go tests pass, but I'm not able to get MetadataViews to update in the Cadence test suite to test against. I believe this is because the contract is included in those deployed to the test environment's service account and I'm not able to run an update on service account contracts in the current release version of Flow CLI. This feature is enabled in current pre-release versions of CLI and should be possible for the v2 branch until the MetadataViews contract is updated in the test suite's auto-deployed contracts.

Looks good! If you want the cadence tests to pass, you can just deploy a new version of the MetadataViews contract and test against that. that is what we do in all the Go tests and in the Cadence 1.0 Cadence tests

Thanks for the tip @joshuahannan! I did exactly that and made relevant changes to test coverage and looks like CI is passing now
